Peers get errors in my multiplayer game

Hey, my name is Faraaz Jan, and although Ive worked with construct for a while now, I have barely touched the multiplayer features. I looked over a few tutorials and sample multiplayer games, and made one of my own, however whenever a peer connects to a game, they get an error "creating world instance without specifying layer" and their screen freezes. However I noticied that although the screen is frozen, you an still control your player using controls, and that shows on the host device. Im using r277, and all the samples ive tested work fine but mine doesnt.

For some reason, cloning the player sprite and changing all behaviours to disabled fixed this, but i noted that for some reason running the same project in construct 3 yield a different result where everything works just fine, even without a cloned player sprite.
